Gemini Sound SDJ-4000 standalone DJ console — 4-channel mixer, dual decks, 7" HD display

Leave the laptop at home. The Gemini Sound SDJ-4000 is a complete two-deck DJ system built into one box — everything you need to walk into a gig, plug in a USB drive, and play. Dual touch-capacitive jog wheels, a 4-channel mixer, pro-level effects, and a 7" HD display that shows you exactly where you are in the track.

Key features

• No computer required — Load your tracks on a USB drive, plug it in, and play. Two internal decks and a full 4-channel mixer live inside the unit, so there's nothing to crash, update, or forget at home.
• Real jog wheels for real scratching — Touch-capacitive, illuminated, and responsive. Vinyl mode gives you the feel you're used to, and slip mode keeps the track running underneath while you work.
• Prep at home, perform anywhere — Pair with V-Case, Gemini's free library management software, to build playlists, set hot cues, and lock in beat grids on your computer. Export to USB and show up ready.
• Effects that do the work — Fast FX for quick one-handed moves (filter, chop, noise, flanger) and Beat FX for bigger transitions (reverb, delay, slice, phaser, and more). All beat-synced and ready to drop in.
• Expandable setup — Link up to two more media players over USB to share libraries and sync decks. Connect turntables, mics, or another SDJ-4000 and build the rig your gig needs.
